3 Claims. (Cl. 83-107) This invention relates to a former folderarrangement for use in connection with rotary web printing presses. Y

N'ational'mag-azines currently contain advertising matter directedtoward specific areas of the country, so that a magazine. issue must bebroken up into regional matter applicable to that region.

-This' makes it necessary, on a press printing three successivesignatures, to print and deliver three different signatures, separatingthem so that they may be introduced into the bindery in the properregional divisions of the issue.

A' folder constructed according to my invention is capable of deliveringthree different signatures on three different deliveries.

Howevenf it is' also desirable, in some cases, to produce threesignatures, each containing different advertising -inatter (possiblyadvertising different products from the} same company), mixed into asingle issue in the same region. The folder shown is also capable ofthis method of delivery.

Broadly, the two'condit-ions are satisfied in this de sign by employingthree deliveries, one of each different--regional division, or byemploying two alternating deliveries, each delivering all three of thedifferent signatures, so that they will be mixed in a single region.

"The'f'object of my invention is to provide a former folder "cylinderarrangement capable of delivering three diiferentsig'riatureson threedifferent deliveries in which it is possible by rearrangement ofelements carried by the respective'cylinder plus the silencing of onedelivery to accomplish amixed signature operation withalternatdeliveries.- f

practical embodiment of my invention is shown in the'accompanyingdra'wing in which FIG. lrepresents diagrammatically an endview of a folder constructed according to my invention in whichsignatures are-strccessively delivered to each of three deliveries, thepitch, line of the, gears for the drive being illustrated in relation tothe respective cylinder;

' FIG. 2 represents an end viewof the embodiment shown .in;FI G 1 withthe respective elements arranged on; their cylinders and with the lowerpin transfer cylinder and the lower gripper delivery cylinder silencedso that the-signaturesare transferred alternately to the two deliveries;and

FIG. 3 represents a front view partly broken away on the work side ofthe frame, said view being partly broken away to show the means forsilencing the lower pin transfer cylinder.

The traveling Web is denoted by 1 and it is passed through the usualforwarding rolls 2, 3 and 4, 5 between the right-hand and left-handcutting and pin transfer cylinders which are denoted respectively by 6and 7.

Located for operative engagement with the right-hand cylinder 6 is anupper gripper delivery cylinder 9 and similarly located with respect tothe cutting and pin transfer cylinder 7 is an upper gripper deliverycylinder 8.

Also associated with the right-hand cutting and pin transfer cylinder 6is a lower pin transfer cylinder 10 located for co-action with a lowergripper delivery cylinder 11.

A right-hand upper delivery 13 is located to receive "ice the productsfrom the grippers on cylinder 9. A similar delivery '14 is located toreceive the products from the grippers on cylinder 11 and a thirddelivery 12 is located to receive the products from the grippers on thecylinder 8.

The right-hand cutting and pin transfer cylinder 6 is provided with pins15, 16, 17 and 18 which are operated in the manner well known in the artand, therefore, no further description of this operation is deemednecessary.

Also on said cylinder 6 are the knife boxes 19 and 20 provided withtheir knives.

On the left-hand cutting and pin transfer cylinder 7 are the pins 21 and22, the knife boxes 23 and 24 plus the knives 25 and 26. It will beunderstood that the terms knives and knife boxes are usedinterchangea-bly.

On the left-hand upper delivery cylinder 8 are the grippers 27 and 28and the boxes 29 and 30 which areadapted to receive grippers when sodesired.

Associated with the transfer cylinder 7 is the usual feed pulley 31.

The upper right-hand delivery cylinder 9 is provided with grippers 32,33 and gripper boxes 34, 3-5 which are adapted to receive grippers whenso desired.

A feed pulley of the usual construction is located for co-action withcylinder 6 and is designated by 36.

The lower pin transfer cylinder 10 is provided with a pin 37 and alsoco-acts with the usual feed pulley 38.

The lower gripper delivery cylinder 11 is provided with grippers 39 and40.

Referring to FIG. 2 the left-hand cutting and transfer cylinder 7 hasadded thereto the pin 41 and the right-hand cutting and transfercylinder 6 is provided with the added knife box 42.

The left-hand upper gripper delivery cylinder 8 has an added gripper 43and the right-hand gripper delivery cylinder 9 has an added gripper 44.

When cylinders 10 and 11 are in operation, hub 54 and gear 55 are boltedtogether by means of a driving plate 56, which is held by bolts 51 and'58. Thus cylinder 10 is driven through driving plate 56. I

To silence cylinders 10 and 11, bolts 51 are removed and placed throughsilencing bar 53 and the extension of plate 56. This now holds cylinders10 and 11 in place. Thus bolts 51 occupy alternate positions dependingupon whether or not the cylinders 10 and-11 are in operation orsilenced.

With cylinders 10 and 11 silenced, hub 54 is free to rotate about gear55.

The pitch lines of the gears for driving the respective cylinders areindicated in FIG. 1 and are designated as 45, 46, 47, 48, 49 and 50.

Referring to the operation of the arrangement shown in FIG. 1 when theformer folder web is ledbetween cylinders 6 and 7 the first signature iscut by the knife 23 and carried by the rotation of cylinder 6 and theassistance of feed pulley 36 to the grippers 33 on cylinder 9 andsubsequently delivered to the endless traveling carrier 13'.

The second signature is out by the knife 26, taken by the pins 16 oncylinder 6 and taken off by the pins 37 on cylinder 10 for subsequentpassage assisted by the feed pulley 38 to the grippers 40 on cylinder11. Delivery from this clyinder is to the endless carrier 14 operated inconjunction therewith.

The third signature is cut by the knife 20 on cylinder 6, taken by thepins 21 on cylinder 7 and assisted by the feed pulley 31 taken by thegrippers 27 on cylinder 8 and delivered to the endless carrier 12.

The fourth signature is cut by the knife 25 and taken by the pins 17 fordelivery to the grippers 32 on cylinder 9 for delivery to endlesscarrier 13.

The fifth signature is cut by the knife 24 on cylinder 7, taken by pins'18 on cylinder 6 transferred to pins 37 on cylinder 10 and thence togrippers 39 on cylinder 11 for delivery to the endless carrier 14.

The sixth signature is cut by knife 19 on cylinder 6, taken by pins 22on cylinder 7 to grippers 28 on cylinder 8 and delivery to the endlesscarrier 12.

It will be understood that this sequence is repeated during subsequentoperation.

It will be understood that the several elements on the several cylindersare not unique in construction being well known in the art, and it willbe understood further that the pockets, A-M, inclusive, in therespective cylinders are normally adapted to receive pins, knives orgrippers as the situation requires without the necessity formodification of same.

The apparatus shown in FIG. 1 is modified to produce the desiredsignatures as illustrated in FIG. 2 by the rearrangement and addition ofthe several elements as follows:

The lower pin trans-fer cylinder is silenced as outlined above. It isalso desirable to remove the feed pulley 38. It is understood that thelower gripper delivery cylinder is also silenced.

With respect to the pocket A on cylinder 7 the knife box is removed andreplaced by the pin apparatus 22. Pocket B is then fitted with the knifebox 23 which has been removed from pocket A.

With respect to pocket C on cylinder 7 the knife box 24 is removed and aspare pin shaft and levers designated generally by 41 are placedtherein.

With respect .to pocket E on the upper gripper delivery cylinder 8 thegrippers 27 are removed and placed in pocket D. Pocket F on saidcylinder 8 is furnished with a set of grippers 43.

With respect to pocket G on cylinder 6 the pin and associated equipmentis removed and replaced with the knife box 19 from pocket H. The saidknife box 19 is replaced with the apparatus 15 removed from pocket G.

The pin shaft andlevers denoted generally by 18 are removed from pocketI on cylinder 6 and replaced with knife box 42.

With respect to pocket L on the upper right-hand gripper deliverycylinder 9 the grippers 32 are removed and placed in pocket K. A spareset of grippers 44 are placed in pocket M of said last named cylinder.

The operation of the arrangement of FIG. 2 as thus equipped is asfollows:

The signature cut at 19, is taken by pins 22 and carried to grippers 28on cylinder 8 which grippers take said signature and deliver same to theendless carrier 12.

The second signature, cut at 26, is taken by pins 16 and carried togrippers 33 on cylinder 9 which grippers take said second signature anddeliver same to end-less carrier 13.

. The cycle is repeated for succeeding signatures by succeeding knivesand pins and grippers, Le, 20, 21, etc.

It will be understood that the lower pin transfer cylinder 10 and thelower gripper delivery cylinder 11 have previously been silenced asoutlined above and that feed pulley 38 has been removed. Otherwise thedrives for the respective cylinders and the means for actuating theseveral elements are as used for the same cylinders illustrated in FIG.1.

Since it is evident that changes may be made in the form, constructedand arrangement of the several parts without departing from the spiritand scope of my invention, I do not intend to be limited to the specificembodiment herein shown and described except as set forth in theappended claims.

What I claim is:
